INDICATING DEVICE.

Application filed December 31, 1925.

This invention relates to indicating devices and more particularly to a device such as a calendar for indicating dates.

The object of the invention is to provide a device of this character which shall be ornamental and attractive in appearance, simple in construction and operation, and which is capable of being used year after year for an indefinite period.

To this end, the device is provided with a pair of cooperating rolls provided on their peripheries with numbers indicative of the day of the month and with suitable legends indicative of the day of the week, respectively. Provision is made for intermittently rotating the rolls in definite relation to one another to bring successive legends and numbers in registration with a marking device to indicate the date. Provision is also preferably made for adjusting the relative position of one roll with relation to the other to accommodate the device to months ofdifferent lengths. These and other features of the invention will be hereinafter described and particularly pointed out in the claims at the end of this specification.

In the drawings, showing the preferred form of the invention, Figure 1 is a front elevation thereof; Fig. 2 is a rear view of the device with one of the cover plates removed; Fig. 3 is a vertical section through the device taken on the line 3-3 of Fig. 2; and Fig. 4 is a horizontal section taken on the line 44 of Fig. 2.

For the purpose of indicating the days of the week and of the month, the device is provided with two cooperating rotatable rolls, one of which is provided on its periphery with equally spaced numerals from 1 to 31 corresponding to the days of the month and the other of which has on its periphery indications of the days of the week, there being preferably twenty-one of such indications, equally spaced, in order on said periphery. These rolls indicated at and 12 respectively in the drawings are enclosed in a casing 14 formed on the rear of the upper portion of a front plate 16, and in order that the rolls may be caused to indicate the desired date, the front plate 16 is provided with two small openings 18 and 20 of such size and so positioned as to permit one of the numbers on the roll 10 and one of the indications of the days of Serial No. 78,681.

is also rota-tably and slidably journaled at its inner end in a hearing, which bears against its lateral surface. This bearing is formed half in a web extending rearwardly from the plate 14 and half in a web 32 extending forwardly from a cover plate 34 provided for'the casing 14.

In order to maintain the rolls 10 and 12 in proper relation to one another, the roll 10 is open on its inner end and has formed on its inner rim crown gear teeth 36, which are normally in mesh with similar teeth 38 formed on the inner rim of the roll 12, which is formed with a central rib and'openat both ends. In the illustrated device, there are thirty-one of these teeth 36 on the roll 10, one for each number marked on the surface of said roll, and there are twenty-one teeth 38 on the roll 12, that is, one for each marking on its surface.

For the purpose of successively rotating, step by step, the rolls 10 and 12 to expose to view through the openings 18 and 20 successive indications of the day and date, the outer rim of the roll 12 has formed thereon ratchet teeth 40 adapted to be engaged by cooperating teeth42 formed on a disk 44. The disk 44 has a central hole 46 by means of which it is rotatably and slidably mounted on the shaft 26. Formed integrally with this disk is a handle 48, the end of which projects through an opening 50 in the cover 34. The crown gear teeth 38 are normally held in engagement with the teeth 36, and the ratchet teeth 42 are held in engagement with the teeth 40 by means of a coiled spring 52surrounding the shaft 26, one end of the spring bearing against the wall 28 and the other againstfa recess in the disk 44 (see Fig. 4). I

There are twenty-one ratchet teeth on both the roll 12 and disk44, that is, one for each marking on the surface of the roll 12 and for each gear tooth on its inner rim. The opening in the plate 34 is just of suflicient length to cau e ea h d n a d, m e ent of the handle 18 to turn the disk A through the space occupied by one ratchet tooth, thus stepping the roll 12 around one ratchet tooth and also through one of its peripheral markings and one of its gear teeth 38. As the latter are in mesh with the teeth 36, the roll 10 will, at the same time, be rotated through the space occupied bv one of its gear teeth, which is equal to the space occupied by one of the numbers on its periphery.

In order to lock the rolls 10 and 12 in adjusted position there are ratchet teeth 54 formed in the periphery of the roll 10 adjacent its outer edge. Cooperating with these ratchet teeth to lock the rolls in position is a pawl 56 held in contact with the teeth by means of a leaf spring 58. he ratchet teeth 5st are thirty-one in number, thus affording means for locking the roll 10 in adjusted position with any one of its numbered divisions visible through the opening 18, and by reason of the intermeshing of gear teeth 36 and 38, at the same time aifording means for lockingthe roll 12 with any one of its lettered divisions visible through the opening 20.

In order that the roll 12 may be rotated relative to, the roll 10 to indicate the day of the week corresponding to the day of the month shown by the roll 10, provision is made for disengaging the gear teeth 36 and 38, so that upon downward movement of the handle 4S'the roll 12 alone will be rotated. For this. purpose, the end of the shaft 26 is extended through the wall 28. A ring 60 is, set into a hole in this extended end of the shaft 26 by means of which the shaft 26, roll 12 and disk M may be pulled to the left (Figs. 2 and 4.) against the pressure of the spring 52, to disengage the teeth 36 and 38. While the parts are held in this posithon, movement of the arm 4-8 and disk 14 effects the roll 12 only, and the latter may thus be adjusted to any desired position with respect to the roll 10.

As shown in the drawings, the device is provided with suitable means for indicating the months. This means comprises in the present case, twelve cards, indicated at 62 in the drawings, one being provided for each month of the year. On each of these cards is printed the month, the year if desired, and any other desired. information of events, such the holirhiys, occurring during that month. The cards 62 are enclosed in a casing 64 formed belon the casing 1i on the rear of the front plate 16 which is provided with a large opening 66 closed by a glass plate 68, the face of one of the cards 62 being visible through said opening, as. shown in lfiig. 1. The cards62 are retained in position in the casing 64 by a hinged cover 70 held in closed position bv lugs 72.

It will be. readily understood that the calendar may be made perpetual by omitting the year from the aforementioned cards, or if it is desired to include the same, a new set of cards may be furnished each year. Also, if desired, enough cards may be provided to extend the life of the device over several yea without addition thereto.

For the purpose of supporting the device in an upright position, suitable feet 74: are provided. As shown in Figs. 2 and 3 these feet are extensions of the side walls of the casing 64:. The device rests, as shown in Fig. 8, on these feet 74 and on the lower edge of the plate 16.
